Replacing a specific material on an object with multiple materials?

I have an object with multiple materials made in Maya. Unity imports it and creates the different materials automatically. I have made my own materials in Unity. When I drag that material onto the object, it replaces the first material assigned to the object.

I can’t figure out how to replace the other materials. Any ideas?
